Does the Transfer Transactions from Receiving to Costing process pick up transactions for all BU's?

Summary: Customer user is running Transfer Transactions from Receiving to Costing which is picking up all transactions including those of Cost Org that they don't have any data access to.

Customer has 2 distinct companies defined within Fusion. Company 1 is purely expensed transactions and using receipt at period end. Company 2 has a mixture of Inventory and expense transactions and is using accrue on receipt.

When user with custom Cost Accountant role (data access only to Company 1 BU's) runs the Transfer Transactions from Receiving to Costing it is also processing the transactions for Company 2 BU/Cost Org.

Their expectation is that the process should only pick up transactions for the BU the user has access to.
